the case of the flat tires


Did some detective work to figure out why I had a flat issues at my last race…I checked the two tubes that went flat and discovered that one of them was from a puncture on the outside (thorn glass or sharp rock) and the other from the inside ( a problem with my rim or rim strip)… I thought I was dealing with one serial puncture…. but I was wrong….two puncture causers were working together to foil my race.

I did some more sleuthing to find a sharp area where the loop of the wheel came together…I sanded down the sharp spot. put a new rim strip on and checked for sharp objects in my tire

Hopefully this mystery is solved… if I get another flat at the Norcross Scurry race this weekend I will reopen the case.
